9 Things About The Human Body You Probably Didn’t Know
Left-handed people have more strength for movements that go counterclockwise. This is why it is much easier for them than a right-handed person to open a jar of jam.
Our bodies are fantastic. He performs thousands of operations every day which, as small as they may seem, are essential to keep us healthy and to feel good.
In most cases, we know the functions of our organism. However, there are many other things that we do not recognize that are of the utmost importance and sometimes even seem unbelievable.
In this article, we are going to introduce you to 9 things about the human body that you probably didn’t know.
1. We have the same amount of hair as chimpanzees
The average body of an adult male contains the same amount of hair (known as down) as a chimpanzee. The difference lies in the thickness of the hair, which is much thinner in humans.
Thus, in our case, the hairs have lost their original protective function. The current situation of body down is probably due to the evolution and use of clothing that protects us from the cold.
2. Why do we have goose bumps?
Everyone has experienced goose bumps many times in their life. It is a pilomotor reflex, a response that humans had in ancient times to bristle body hair and protect themselves from the cold or other dangers like animals.
It was in fact a magnification of the waist. Of course, this function is now obsolete. Although we don’t have so much body hair anymore, our skin still has the same response.
3. Years of blinking
Humans spend the equivalent of 5 years blinking. As we know, this action is very important for our eyes: it is a mechanism of protection and prevention.
Thanks to this, we lubricate and rest our eyes, which cannot stay open all the time. Blinking is also a protective reflex since we usually do this when something is pointed at our face.
4. Lefties are stronger
Maybe it’s physics, left-handed people have more strength when they apply it counterclockwise.
This means that for a left-handed person, it will be easier to open a jar than for a right-handed person. However, to close the same jar, where it will be necessary to apply force in the opposite direction, the right-hander will have an easier time doing so.
5. The stomach stores acid
Our stomach stores hydrochloric acid, which is produced by cells in this area. In industry, this type of acid is highly corrosive and is used in metallurgy.
However, the lining of the walls of the stomach lining protects us from the harmful effect of the acid, and we do not suffer from it at all.
6. We are a repository of bacteria
The human body is a huge repository of bacteria. In fact, calculations say there are many more cells – about 10 times more than cells.
Of course, this does not mean that all bacteria in our body are harmful to health. There are different, some are beneficial and help our body to maintain good health.
7. Naps are good
Taking a 20-minute nap is good for you. It helps us improve our focus, mood, and productivity. However, sleeping too long during the day can have negative consequences. For example, we may feel more tired and irritable.
8. Lots of dead cells
Every day, our body rejects a large amount of dead cells, mainly from our skin. It hunts so much that if we put them together for a year, we would get about 2 pounds of dead skin cells.
9. Sensitivity
As we know, the human body has a large amount of nerve endings that allow us to feel things. Of these, the most sensitive are found on the lips and fingers, while the least sensitive are found in the mid-back area.
